In some parts of the world, record numbers of people are being diagnosed with attention deficit hyperactivity disorder (ADHD). In the United States, for example, government researchers last year reported that more than 11% of children had received an ADHD diagnosis at some point in their lives1 — a sharp increase from 2003, when around 8% of children had (see ‘ADHD among US boys and girls’).Why is autism really on the rise? What the science saysBut now, top US health officials argue that diagnoses have spiralled out of control. In May, the Make America Healthy Again Commission — led by…

As global policymakers and healthcare advisers move to curb ultra-processed foods (UPFs), the UK medical journal The Lancet has published a three-part series outlining policy recommendations to regulate and reduce these products, underscoring that education and consumer-focused behavioral shifts are still insufficient to address the public health threat. “This rise in UPFs is driven by powerful global corporations who employ sophisticated political tactics to protect and maximize profits,” stress The Lancet authors. “Deteriorating diets are an urgent public health threat that requires coordinated policies and advocacy to regulate and reduce UPFs and improve access to fresh and minimally processed foods.”Challenging…

The holidays can make managing blood sugar challenging. Having an advance party plan can help.Start with a good night’s sleep the night before and eat balanced meals throughout the day. Then, plan out what you’ll eat and drink at the gathering, and take a short walk afterward. Holiday celebrations may be merry. But for some of us, there’s a downer in the room: Managing blood sugar. “Foods [you eat during] the holiday season can set your blood sugar on a roller coaster of highs and lows,” says Mia Syn, M.S., RDN. Why? The special foods that are plentiful during the holidays,…

At Thanksgiving dinner, lucky families will avoid impassioned discussions about religion and politics. But another argument is almost inevitable: white meat versus dark meat.Light meat lovers claim dark meat is greasy; dark meat devotees complain that light meat is dry and lacks flavor. Few meat eaters are ambivalent on the matter.But why do these different types of meat exist, and what underlies these differences? As a muscle physiologist, I can tell you it comes down to the metabolic and functional differences between various types of muscle.Consider how turkeys move. Have you ever seen a flock of turkeys fly by? Of…

Medicare finalizes reimbursement for CaRi-Plaque, giving hospitals and clinics a unified route to adopt AI-powered coronary plaque analysis. The use of AI in cardiovascular imaging took a major step forward as the Centres for Medicare & Medicaid Services (CMS) confirmed new national reimbursement for CaRi-Plaque, Caristo Diagnostics’ AI-based coronary plaque analysis. From 1 January 2026, hospitals will be able to bill Medicare $950.50 for CaRi-Plaque under the Hospital Outpatient Prospective Payment System (OPPS). This follows CMS’s recent decision to set a 2026 Physician Fee Schedule (PFS) rate of over $1,000 for the same procedure in physician offices and imaging centers,…

Between the holidays and cooler temps, people may eat less fresh produce, which means less fiber.Eating fibrous seasonal produce, such as Brussels sprouts and pumpkin, can help you stay regular and prevent constipation. Staying active and drinking plenty of fluids are also key ways to promote healthy digestion. If you deal with regular constipation, you already know how uncomfortable and disruptive it can be. But winter often stacks the deck: shorter days, less movement, fewer produce-packed meals and more comfort-food cravings can all contribute to sluggish digestion. “Many people tend to lean into comfort foods during the winter months and eat…

Sensor dot readoutReadout of the exchange-only qubits is performed through PSB41, in which an electron either tunnels or remains confined, depending on its spin state. Nearby sensing dots, which function as single electron transistors (SET), are capacitively coupled to the quantum dot electrons and the conductance of SET will change depending on whether a charge tunnels or not. In this set-up, the change in the SET conductance is detected using a heterojunction-bipolar-transistor-based cryogenic amplifier42. The amplifier and SET are embedded in a lock-in detection circuit in which signals of around 50 μVrms at 1 MHz are biasing one ohmic of the SET…

Krill oil is a good source of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), two key types of omega-3 fatty acids.[4] “Omega-3 fats are beneficial for heart, brain, and cell health,” says Vicki Shanta Retelny, RDN, who is based in Chicago.“Krill oil can be used as an alternative to fish oil and has some compelling benefits,” adds Sarah Kamely, RDN, who helps clients with an integrative approach in Miami.1. It May Support Heart HealthChronic (ongoing) inflammation is linked to several diseases, including heart disease, so the anti-inflammatory effects of krill oil may help your heart stay healthy. Polyunsaturated fatty acids like…

Dairy and eggs are two nutritious foods that deliver protein, but not everyone can eat them or chooses to. Protein requirements vary by many factors, including age and activity level.Other high-protein foods to help you hit your goals include seafood, poultry, beans and tofu. Protein is an essential macronutrient for building muscle, maintaining an efficient metabolism and keeping you full between meals. But you don’t need dairy or eggs to meet your daily needs. Whether you’re lactose-intolerant, follow a vegan diet, or prefer to avoid these options, there are plenty of protein-rich dairy-free and egg-free choices available. “It’s entirely possible to…
